Clay Walker Expecting Baby No. 6, a Daughter with Wife Jessica

Clay Walker and his wife Jessica are going to be parents for the 6th time.

The 53-year-old country musician and his wife Jessica are expecting their sixth child, a daughter, this fall, he said on Tuesday.

"We are beyond excited about having a little girl!" Walker states in a press release.

"Her brothers and sisters are awaiting her arrival. God is great!"

The couple's new child will join their existing family of daughters Mary-Elizabeth, 13, sons Christiaan, 2, Ezra Stephen, 5, Elijah Craig, 10, and William Clayton, 14, as well as Walker's adult daughters Skylor and MaClay from a previous marriage.

In addition to anticipating the arrival of baby No. 6, the 'If I Could Make a Living' singer is also marking the 30th anniversary of his illustrious career, which has seen him achieve 11 No. 1 singles, 32 songs on the Billboard charts, four RIAA Platinum albums, and two Certified Gold albums.

Walker's Country Side Tour began in February and will last until the end of July.

Before Christiaan, the "Need a Bar Sometimes" singer revealed to PEOPLE that Mary-Elizabeth initially desired a sister but swiftly changed her mind about having a second brother in the picture.

"The shock of it being another boy, for Mary, it lasted a couple of hours. There were some tears shed, I won't lie," Walker said with a laugh. 

"It was because of expectation, but that was overcome with the thought that we're not in control of that. We don't decide if it's a boy or girl, and she was able to understand that after a while."
